Ultrasound

Ultrasound refers to mechanical vibrations which are essentially the same as sound waves but of a higher frequency. The sound waves involve vibratory motion of molecules. This vibration creates energy and movement which in turn creates heat.

Therapeutic Effects:-

Heating can decrease pain and muscle spasm

Heating structures such as joint capsule, ligaments, tendons and scar tissue can increase their extensibility and hence decrease joint stiffness

Increases the strength of collagen tissue

Encourages the growth of new capillaries in ischaemic (no blood supply) tissue

Promotes bone healing and growth, especially in a non-union fracture

Breaks up scar tissue

Can be used to help diagnose stress fractures

The heating of the tissues increases blood flow for promoting tissue healing
